compression settings in the sequence
on Apr 10, 2010 at 9:59:18 am

Hello,
I am working with a timeline of clips H.264 (128x720p, 30fps).
The sequence is set with the same parameters even if I set the compressor NONE instead of H.264.
There are drawbacks? I thought the final output, not recompress (exporting with SAME SEQUENCE AS) may have advantages .. but .. I do not see eye to some elucidation on the choice of compression settings in the sequence?
thank you very much

Hi gabriele,
H264 is not an editing codec.
Depending of the mood of FC you may be able to cut and export without problem, but a soon as you want to do anything else (filters, motion,..) probably FC will start to miss behave.
Your best option is transcoding your footage to an editable Intraframe codec (Prores may be the best option).

thanks rafael..
i managed to edit the entire project with h264 clips without transcoding, adding all effects..of coure playback ain't that smooth..is it right to finally export in h264 so it will no recopress the whole (compression sequence settings set to NONE)?

NONE is probably one of the worst option. 8b RGB and the biggest files in the world.
Change the sequence codec to Prores.
Try to get a good Prores master and then convert that one to H264 in Compressor.
Try to put the things easy for FC.

Hi Gabriele,
Yes, set your sequence codec to Prores instead of NONE.
The rendering will be done in YUV (as your footage) instead of RGB.
The files will be much smaller and you will be able to play them in RT (impossible with NONE).
